Laminated Glass

The structure which is formed by combining a glass sheet with an intermediate layer through another glass sheet under the influence of temperature and pressure is called laminated glass.

DÜZCE CAM uses PVB (polyvinyl butiral) as interlayer in all laminated glass. In this way; laminated safety glass, which provides high heat and sound insulation, is impact-resistant, and prevents dispersion of glass pieces in the event the glass breaks, reduces the risk of injury in case of cutting or sinking, is produced. The laminated safety glass produced in accordance with TS EN 12543-2 standard is used in many applications such as showcases, bank branches, shopping malls, hospitals, museums, etc., and especially in heat insulation glass.

Having started the laminated safety glass production journey in 2012 with its production capacity of 630,000 m2/year, DÜZCE CAM has obtained an important position in the national and international laminated glass production market by commissioning the second laminated glass production line with a capacity of 1,676,000 m2/year in May 2017.

Acoustic Laminated Glass

Acoustic laminated glass is designed with the aim of provide sound insulation of the buildings and structures in areas with high sound and noise. Having sound insulation feature used between glass plates, acoustic PVB interlayer absorbs, weakens the sound waves with high frequency coming from outside and serves as a noise barrier. By this means, the quality of life is increased by creating a quiet environment in spaces, and stress and other diseases caused by noise are prevented.

Opaque Laminated Glass

Opaque laminated glass has a PVB interlayer of dull color, which ensures non-display of the interior space, unlike other laminated glass. It can be preferred for security purposes like other laminated glass products, and prevents the color of the household goods such as curtains, furniture and carpets from fading by absorbing the ultraviolet rays having short wavelengths of the sun. Opaque laminated glass can also be produced with PVB interlayers of various colors in order to provide special lighting effects or to create decorative and environmental arrangements.

Opaque Laminated Glass

• It minimizes the risks caused by glass breakage by holding the pieces firm in case of glass breakage.
• It is used for the protection of lives and properties against the external impacts as well as for the prevention of the injuries due to any accident.
• It prevents/delays intrusions during attempted attacks and thefts with some tools such as stones and sticks according to PVB, glass thickness and the size of the external effect.
• It contributes to the sound and heat insulation.
• It prevents fading of items as it prevents the passage of UV rays.
• It ensures privacy in spaces with opaque laminated glass of different colors as well as provides an aesthetic appearance.

  • Properties of Light

    Light Transmittance: This is the percentage of the light coming from the glass, which passes through the glass.

    Light Reflection (external): This is the percentage of the light coming from the glass, which is reflected back by the glass.

    Total Transmittance of Solar Energy: This is the percentage of the total solar energy coming onto the glass, which gets in. Lower total transmittance value for solar energy refers to better solar control.

    Thermal Transmittance: It is the criterion of thermal insulation on glass. Lower U value means better heat insulation and less heating-cooling costs.

    Correction Factors

    C and Ctr Spectrum adaptation values assess the suitability of construction components with respect to exposure to specific sounds. These correction factors, called C and Ctr spectrum adaptation values, reduce the Rw sound insulation measurement connected with the noise generated according to the EN table of the structure component.

    For example: A structure component with a value of Rw (C, Ctr) = 36 (-1, -2) has a insulation performance of 36 dB. The sound insulation is 1 dB for higher frequency noise resources, and it is 2 dB for the lower frequency resources.
